The six-strong team set off from Land's End on June 12 and was due to reach John O'Groats earlier this week.

Three of the cyclists taking part in the 1000-mile marathon suffer from the condition, including team leader David Greaves.

The 64-year-old, from Ripon, in North Yorkshire, was diagnosed with Parkinson's six years ago.

He explained that as the event was being supported by Archbishop of York, John Sentamu, patron of the Parkinson's Disease Society, the cyclists' route had taken in 12 cathedral cities, including Truro, Exeter, Salisbury, York, Ripon and Edinburgh.

In addition, the bikers had even been afforded a fly-past by the RAF when they were in Ripon.

"Riding a bike from one end of the country to the other is quite a challenge, but that is not what this ride is about," explained David.

"It is not about bikes. It's about funding a cure for Parkinson's Disease.

"At every stop en route, we have passed on our message that research into a cure for Parkinson's Disease is in its end-game phase - it will happen, Parkinson's Disease will be cured."

For the Berwick to Edinburgh leg of the journey, the cyclists were joined by Andrew Sim, the Scottish regional organiser for the Parkinson's Disease Society.

David said the cyclists had planned to average 50 miles a day, but on some legs, this had increased to as many as 80 miles.

Parkinson's dramatically affects a person's movement and many people with the condition have no movement at all without their medication.

To highlight this, David said the three members of the team suffering from the disease had to take a total of 31 pills every day, just to enable them to complete the challenge.

Parkinson's can affect anyone at any time at any age.

It is estimated that more than 120,000 people live with this crippling degenerative neurological disorder in the UK, with 10,000 new sufferers diagnosed each year.

David explained that only a fraction of sufferers belong to the Parkinson's Disiease Society, which meant many were fighting the condition without the support of others in the same position.
